C#

• Why is it important to use a capital 'M' in the main function?

  Because C programming language is case-sensitive.
• What command can you use to prevent the console from closing immediately after running a program?

  Use console.readLine().
• What does the console.writeLine() function do?

  It prints text to the console.
• How do you declare an integer variable in C?

  Use the syntax int variableName = value.
• What is the difference between declaring and initializing a variable?

  Declaring a variable means defining its type, while initializing means assigning it a value.
• How can you declare multiple integer variables in one line?

  Use the syntax int x, y, z;.
• What is the maximum value of an integer in C?

  It is approximately 2.1 billion.
• How do you denote a long integer in C?

  By placing a capital 'L' at the end of the number.
• What is the maximum value of a double in C?

  Approximately 1.7e+308.
• How do you declare a float variable in C?

  By placing a capital 'F' at the end of the number.
• What is the purpose of using a capital 'M' at the end of a decimal number?

  To denote that the number is a decimal type.
• What is the maximum value of a decimal in C?

  It is approximately 79,228,162,514,264,337,593,543,950,335.
• How does declaring multiple variables in one line improve code readability?

  It reduces the number of lines of code and keeps related declarations together.
• If you want to print the value of a variable, what command should you use?

  Use console.writeLine(variableName);.
• What happens if you forget to use a capital 'M' in the main function?

  The system will not recognize the main function, resulting in an error.
• What is the purpose of the console.readLine() command?

  It waits for user input before closing the console.
• Why is it important to understand data types in C programming?

  Data types determine the kind of data a variable can hold and how much memory it uses.
• How do you differentiate between an integer and a long in C?

  An integer is typically 32 bits, while a long is usually 64 bits.
• What should you do if you want to declare a variable and assign it a value in separate lines?


  Declare the variable first, then assign it a value on the next line.
• What is the significance of the curly braces in a C program?

  They define the scope of classes and functions.
• What is the first command to write in a C program to prevent the console from closing?


  Use console.readLine();.
• How do you print a string in C?

  Use console.writeLine("Your string here");.
• What is the relationship between variables and data types in C?

  Variables are containers for data, and data types define the kind of data that can be stored in those containers.
• If you want to create a variable that can hold a decimal number, which data type should you use?

  Use the double or float data type.
• What is the purpose of the console class in C?

  The console class provides methods for input and output operations.
• What is the syntax to declare a variable in C?

  DataType variableName = value;
• Why is it important to initialize variables in C?


  Initializing variables ensures they have a defined value before use.
• How does the use of comments improve code quality in C?

  Comments explain the purpose of code sections, making it easier to understand and maintain.
• What should you do if you want to change the value of a variable after it has been declared?

  Simply assign a new value to the variable.
• What is the significance of the main function in a C program?

  It serves as the entry point for program execution.
• What is the command to print "Hello World" in C?


  console.writeLine("Hello World");.
• How do you handle errors in C programming?


  By using exception handling techniques.
• How does debugging contribute to software development?


  Debugging helps identify and fix errors, improving software reliability.
• What is the first step to take when debugging a C program?


  Use Visual Studio's debugging tools to identify bugs.
• What is object-oriented programming in C?

  It is a programming paradigm based on the concepts of classes and objects.
• What are the key principles of object-oriented programming?

  Classes, objects, inheritance, and polymorphism.
• How does object-oriented programming improve code quality?

  It promotes modular and maintainable code.
• How do classes and objects relate in object-oriented programming?

  Classes are blueprints for creating objects.
• What should you do to create a modular program in C?

  Use classes and functions to organize code effectively.
• What is the purpose of a decimal in programming?

  To represent fractional numbers.
